snow fleas covered the snow on a warm day in march in the town of New Marlborough Ma. According other web sites they are not fleas and they don't bite but eat stuff that pokes thru the snow like tree trunk moss and end up in deer tracks because they can't get out by flicking their tail. that is how the move. What other creature shares that locomotive affectation? they somehow don't freeze, maybe because they eat sap or are full of sugar or something??
